Study of Wear Properties of In Situ TiB/TiC Reinforced Ti1100 Composites

The tribological performances of in-situ (TiB + TiC) / Ti1100 composites prepared by casting and the matrix alloy were tested by pin-on disc mode. The worn surface and wear debris were investigated by SEM. The models of the composites during the wear process were simulated by ABAQUS FEA software. The analysis shows the stress distributions inside the composites under the different shear stress. The wear mechanism of the composites is probed.
